DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following part will illustrate exemplary embodiments of the present disclosure with reference to the drawings, including various details of the embodiments of the present disclosure for a better understanding. The embodiments should be regarded only as exemplary ones. Therefore, those skilled in the art should appreciate that various changes or modifications can be made with respect to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, the descriptions of the known functions and structures are omitted in the descriptions below.

In a related art, an obstacle is usually detected using a single obstacle detection method. For example, a laser radar may be used to detect the obstacle, and an obstacle detection result of the laser radar is used as a final obstacle detection result; or, an image captured by a camera on an autonomous vehicle may be processed to obtain an obstacle detection result which is used as the final obstacle detection result.

However, the single obstacle detection method may have a problem of inaccurate detection.

FIG. 1 is a schematic diagram according to a first embodiment of the present disclosure, and the present embodiment provides a method for detecting obstacle, including:

-   101: detecting an obstacle in a vehicle traveling process using     plural obstacle detection manners to obtain plural initial detection     results of the obstacle, the plural initial detection results     corresponding to the plural obstacle detection manners. -   102: fusing the plural initial detection results to obtain a fusion     result. -   103: determining a final detection result based on relevance     information among plural obstacle sensors, the plural obstacle     detection results and accuracy of the plural obstacle detection     results.

A vehicle may be an autonomous vehicle, or a vehicle having an advanced driving assistance system (ADAS).

The plural obstacle detection manners may include: a ranging-based obstacle detection manner, an obstacle detection manner based on computer vision, or the like.

The ranging-based obstacle detection manner may be performed using a ranging detection device on the vehicle, and the ranging detection device includes, for example, a laser radar, a millimeter wave radar, or the like.

In the obstacle detection method based on computer vision, environmental images around the vehicle may be collected by a camera on the vehicle, and subsequently processed by a processor of the vehicle, or the environmental images are sent to a cloud by the vehicle and subsequently processed by the cloud, thereby obtaining an obstacle detection result based on the computer vision.

Taking the autonomous vehicle as an example, assuming that the plural obstacle detection manners include the ranging-based obstacle detection manner and the obstacle detection manner based on computer vision, and a ranging operation is performed based on the laser radar, as shown in FIG. 2 , the laser radar, the camera, or the like, may be mounted on the autonomous vehicle, such that one detection result may be obtained by the laser radar on the autonomous vehicle, and another detection result may be obtained by the camera on the autonomous vehicle. For distinction, the detection results at this point may be referred to as the initial detection results, and further, the detection result obtained by the laser radar may be referred to as a first initial detection result, and the detection result obtained by the camera may be referred to as a second initial detection result.

Further, as shown in FIG. 2 , after obtained, the plural initial detection results may be fused to obtain the fusion result, and then, the final detection result may be obtained based on the fusion result.

In some embodiments, each of the plural initial detection results is used to indicate whether an obstacle exists, and the fusing the plural initial detection results to obtain a fusion result includes: selecting an initial detection result used to indicate existence of the obstacle from the plural initial detection results as a to-be-processed detection result; obtaining fusion information of the to-be-processed detection result; and obtaining the fusion result based on the fusion information of the to-be-processed detection result.

The initial detection result may be 1 or 0, 1 indicating the existence of the obstacle, and 0 indicating inexistence of the obstacle.

Assuming that there exist three initial detection results which are represented as a first initial detection result, a second initial detection result and a third initial detection result respectively, if the first initial detection result is 1, the second initial detection result is 1, and the third initial detection result is 0, the to-be-processed detection results are the first initial detection result and the second initial detection result.

Then, fusion information of the first initial detection result and the second initial detection result may be obtained, and the fusion result may be obtained based on the fusion information.

By selecting the initial detection result for indicating the existence of the obstacle from the plural initial detection results and subsequently processing the selected initial detection result, a processing amount may be reduced, and a processing efficiency may be improved.

In some embodiments, there exist plural to-be-processed detection results, and the fusion information of the to-be-processed detection results includes: accuracy information of each of the plural to-be-processed detection results and relevance information between every two of the plural to-be-processed detection results; and the obtaining fusion information of the to-be-processed detection result includes: detecting environmental information of the vehicle by a pre-established accuracy detection model to obtain the accuracy information of each to-be-processed detection result; and obtaining relevance information between every two obstacle detection manners corresponding to the every two to-be-processed detection results from a pre-configured configuration file, and taking the relevance information as the relevance information between the every two to-be-processed detection results.

Assuming that the to-be-processed detection results include: the first initial detection result and the second initial detection result, the accuracy information of the first initial detection result and the accuracy information of the second initial detection result may be obtained, and in addition, the relevance information between the first initial detection result and the second initial detection result may be obtained, and the accuracy information and the relevance information are used as the fusion information.

The accuracy detection model may be pre-established, the model may be a multi-layer perceptron (MLP) model, input of the model is the environmental information corresponding to the autonomous vehicle, and output thereof is the accuracy information corresponding to various obstacle detection manners among the plural obstacle detection manners of the autonomous vehicle.

The model may be obtained after a training operation using historical environmental information and corresponding label information, and the label information may be obtained after the accuracy information of various obstacle detection manners corresponding to the historical environmental information is manually marked.

The environmental information corresponding to the autonomous vehicle may include: weather conditions (sunny, rain, snow, or the like), light intensity, rain intensity, snow intensity, fog intensity, a temperature, a vehicle speed, an obstacle speed, a distance from the obstacle, or the like.

The above-mentioned environmental information may be obtained by detection of a sensor on the vehicle, or obtained by the vehicle from the cloud.

For example, the plural obstacle detection manners correspond to the laser radar and the camera respectively, and the accuracy of the initial detection result corresponding to the laser radar and the accuracy of the initial detection result corresponding to the camera under the current environmental information may be obtained by the accuracy detection model. Assuming that the accuracy detection model is a MLP model, the accuracy of the initial detection result corresponding to the laser radar is represented by Px, and the accuracy of the initial detection result corresponding to the camera is represented by Py, the MLP model may process the environmental information and output Px and Py, as shown in FIG. 3 .

In addition, the configuration file may be stored in the cloud or the vehicle, and relevance information between different obstacle detection manners may be pre-configured in the configuration file; for example, the relevance information between the detection method corresponding to the laser radar and the detection method corresponding to the camera may be configured, and then, the relevance information may be used as the relevance information between the corresponding initial detection results.

The two obstacle detection manners are taken as an example in the above description, and it may be understood a similar processing operation may be performed for more obstacle detection manners. For example, for three obstacle detection manners of the obstacle detection method corresponding to the laser radar, an obstacle detection method corresponding to the millimeter wave radar, and the obstacle detection method corresponding to the camera, the initial detection results corresponding to the three obstacle detection manners are a first initial detection result, a second initial detection result, and a third initial detection result respectively. If all the three initial detection results indicate that the obstacle exists, for example, are 1, the accuracy information of the first initial detection result, the accuracy information of the second initial detection result, and the accuracy information of the third initial detection result may be obtained by the accuracy detection model. In addition, relevance information between the obstacle detection method corresponding to the laser radar and the obstacle detection method corresponding to the millimeter wave radar, relevance information between the obstacle detection method corresponding to the millimeter wave radar and the obstacle detection method corresponding to the camera, and relevance information between the obstacle detection method corresponding to the laser radar and the obstacle detection method corresponding to the camera may be pre-configured in the configuration file, and then, a fusion processing operation may be performed based on the three types of accuracy information and the three types of relevance information to obtain the fusion result.

By the accuracy detection model and the configuration file, the corresponding accuracy information and the corresponding relevance information may be obtained adaptively.

In some embodiments, there exist plural to-be-processed detection results, and the fusion information of the to-be-processed detection results includes: accuracy information of each of the plural to-be-processed detection results and relevance information between two of the plural to-be-processed detection results; and the obtaining the fusion result based on the fusion information of the to-be-processed detection results includes: sorting the accuracy information of all the to-be-processed detection results in a descending order to obtain sorted accuracy information; and obtaining the fusion result using a preset functional relationship based on the sorted accuracy information and the relevance information between every two to-be-processed detection results, the preset functional relationship being used to indicate a relationship between the fusion result and the accuracy information and the relevance information.

The accuracy information may be divided into a first part and a second part, and the relevance information is relevance information between the first part and the second part. In the preset functional relationship, the fusion result is in a direct proportion relationship with one of the two pieces of accuracy information and a product of the other of the two pieces of accuracy information and the relevance information.

Further, for two to-be-processed detection results, each of the first part and the second part may be one to-be-processed detection result. For three or more to-be-processed detection results, the second part may be one to-be-processed detection result; the first part may include a variable number of to-be-processed detection results, and an initial value is one to-be-processed detection result, and then may be increased step by step.

Specifically, assuming that the two to-be-processed detection results are represented by x and y respectively, the corresponding accuracy information is Px and Py after sorted in a descending order, the relevance information of the two to-be-processed detection results is represented as Rxy, and the fusion result is represented by P, a calculation formula of the fusion result P may be as follows:

P=1-(1-Px)*(1-Py*Rxy).

wherein Px, Py and Rxy are values within [0, 1].

Assuming that the two to-be-processed detection results are the initial detection result corresponding to the laser radar and the initial detection result corresponding to the camera respectively, if the accuracy information of the initial detection result corresponding to the laser radar is 0.8, the accuracy information of the initial detection result corresponding to the camera is 0.9, and the pre-configured relevance information between the two initial detection results is 0.1, the fusion result P is as follows through the above operation:

P=1(1-0.9)*(1-0.8*0.1)=0.972.

Taking three to-be-processed detection results as an example, assuming that the three to-be-processed detection results are represented by x, y and z respectively, corresponding accuracy information is Px, Py and Pz after sorted in a descending order, relevance information between every two of the three to-be-processed detection results is represented as Rxy, Rxz and Ryz, and the fusion result is represented by P, a calculation formula of the fusion result P may be as follows:

Pxy=1-(1-Px)*(1-Py*Rxy);

P=1-(1-Pxy)*(1-Pz*Rxyz)

wherein Rxyz is selected to be a smaller value of Rxz and Ryz.

Px, Py, Pz, Rxy, Rxz and Ryz are values within [0,1].

By sorting the accuracy information and calculating the fusion result based on the sorted accuracy information and the relevance information, the accuracy of the fusion result may be increased.

In some embodiments, the obtaining a final detection result of the obstacle based on the fusion result includes: if the fusion information is greater than or equal to a preset threshold, determining that the final detection result is the existence of the obstacle.

Taking the above fusion result P=0.972 as an example, if the preset threshold is 0.5, since 0.972 is greater than 0.5, an obstacle exists at this point.

Otherwise, if the fusion information is less than the preset threshold, it is determined that no obstacle exists at this point.

By comparing the fusion information with the preset threshold, the final detection result may be determined simply, conveniently and efficiently.

Further, the autonomous vehicle may perform a corresponding operation based on the final detection result of the obstacle; for example, when the final detection result is the existence of the obstacle, a braking operation may be performed.

In the embodiment of the present disclosure, the plural initial detection results are obtained using the plural obstacle detection manners, the initial detection results are fused, and the final detection result of the obstacle is obtained based on the fusion result, thereby realizing the fusion of the plural obstacle detection manners, and improving obstacle detection accuracy.
